NASTY cold gearchange (Read 671 times)

JamesV6CDX Ex Member Gender: Drives: 2002 (02) 3.2 Retail MV6 in Star Silver with Leather	NASTY cold gearchange 13. Jan 2007 at 21:50 Question relates to my V6 Meega ~~dog~~ workhorse. Over the last few days, when setting out in the mornings, the automatic gearchange is VERY jerky, makes a horrible noise and he whole car shudders. Drive half a mile or so, and it's absolutely fine. Autobox shagged? I changed the autobox fluid about 3 months ago.

Check the level again as a first....

Jan 2007 at 22:21 so after 10 mins, starting off from a stand still its fine?? Suggests the box is fine really if its ok when warm? - Does it rev high before the changes?

lachleaves Newbie Offline As fruity as the car itself Posts: 18 Anglesey Gender:	Re: NASTY cold gearchange Reply #6 - 14. Jan 2007 at 11:46 It deliberately stalls the gearchange when cold to heat up the catalytic convertor anyway doesn't it? Hence after 5 minutes or so, when it's warmed - it appears fine.

Jan 2007 at 17:25 Mine is a bit jerky for the first few minutes as well, but doesn't make any nasty noises. Only happens when really cold and been stood overnight. I gather that this is normal. Does updating the software on the gearbox ECU smooth this out?

From my own experience, and reports of others, all changes are smoother...
